An epidemic of hydrophobia brought on by “mad wolves” seems to have contributed to the early break-up of the 1833 meeting. Campbell, Wyeth, and the partners of the Rocky Mountain Fur Company with fifty-five packs of beaver and a strong guard circled down through South Pass and up to the junction of the Shoshone and the Bighorn rivers, where they embarked on bullboats for the mouth of the Yellowstone. Here Wyeth was entertained at the palatial Fort Union by the famous Kenneth McKenzie, and observed a powder flask which had belonged to the unfortunate More, and which had found its way here from Jackson’s Hole by the devious channels of the fur trade. While Bonneville outfitted an expedition under Joseph R. Walker to explore California (and discover Yosemite Valley), the American Fur Company brigades headed for the Snake River country. On July 20 Warren A. Ferris and Robert Newell departed at the head of an outfit destined for the Flathead trade. The little party consisted of six “engages” with pack horses, and five armed Indians, amounting in all to thirteen armed men. Their route was the usual one via Hoback Canyon and Teton Pass. The ecstatic description of Jackson’s Hole from the summit of the pass, given by Ferris on this occasion, is one which can be appreciated by the modern tourist: ... Gazing down in the direction of Jackson’s Hole, from our elevated position, one of the most beautiful scenes imaginable, was presented to our view. It seemed quite filled with large bright clouds, resembling immense banks of snow, piled on each other in massy numbers, of the purest white; wreathing their ample folds in various forms and devious convolutions, and mingling in one vast embrace their shadowy substance.—Sublime creations! emblems apt of the first glittering imaginings of human life!... Turning with reluctance to things of a more terrestrial nature we pursued our way down to Pierre’s Hole, where we fortunately discovered and killed a solitary bull.... The rendezvous of 1834 was scheduled for June on Ham’s Fork of the Green near present Granger, Wyoming; and here converged all the scattered trapper bands, with the exception of those in the pay of Bonneville, who had his own private rendezvous on Bear River. Drips hunted up the Snake River to Jackson’s Hole, and apparently crossed into the valley of the Green from there. Behind him came Ferris. On his southward journey from Montana country, Ferris decided to make a side trip from Henry’s Fork to investigate strange rumors concerning the upper Madison, a trip which resulted in the second known published description of the Yellowstone Park wonders.
